You'd have to go with triple G but canelo would make it entertaining whilst it's last with his quick combos. Problem is he works in spurts & can't sustain his work . Golovkins pressure is relentless and canelo would find himself working hard out of his comfort zone to keep Golovkin off him. Another problem canelo has is that jus feet are too slow and heavy to keep moving so if he can't get out the way of the bombs like murray did for afew rounds then I see him absorbing too many & getting stopped
